REGISTER.

SPECIFICATION forming part of Letters Patent No. 633,455, datedSeptember 19, 1899.

Application filed March 25, 1898.

To @ZZ whom, it muy concern:

Be it known that I, OYRUS S. HOOD, a citizen of the United States,residing at Corning, in the county of Steuben and State of New York,have invented certain new and useful Improvements in Registers, of whichthe following is a specification.

My invention relates more particularly to improvements infloor-registers; and the objects of my improvements are, first, tosimplify and cheapen the construction of such registers; second, torender the surface plate easily removable for the purpose of cleaningout the dust, dsc., which will accumulate in the register-box; third, toprovide for the ready insertion of a carpet beneath the border of thesurface plate, and, fourth, to permanently attach a valved register-boxto the floor and to the heater-pipe connection. I accomplish theseobjects by the construction and arrangement of parts illustrated in theaccompanying drawings, in which- Figure l is a vertical section throughthe center of my improved register and registerbox; Fig. 2, a similarsection on the line o3 0c in Fig. l, and Fig. 3 a modified form of theinvention. Y

Similar letters refer to similar parts in the three views.

A represents a square or oblong box from which depends a cylindricalsleeve B, to which is connected the pipe from the heater. The box A isprovided with flanges or lugs O, which are let into the iioorD andpermanently secured thereto. The box, however, may be secured to theiiooring in other desirable ways, as by screws or nails through thesides or at the bottom of the box. The fretwork surface plate E isprovided with depending flanges or lugs which fit into the opening atthe top of the box A to secure it in position, or it may be removablysecured thereto by means of screws. This surface plate is provided witha broad border, and the carpet F may be cut and folded so as to come upover the flanges O and underneath this border of the surface plate.

quired to be cut to a less extent than is the ordinary practice, and bythus setting the surface plate over the edge of the carpet a much neaterappearance is produced and the carpet is, permanently secured in placearound By this arrangement the carpet is re- Serial No. 675,185. (Nomodel.)

the register-plate,with its edge protected from wear.

In the sleeve B, I preferably locate a butterfly valve or damper G,pivoted in the sleeve by means of the rod H, which is set at one side ofthe vmedial line of the valve in order that the valve may be heavier onone side of itsaxis thanon the other. The rod H, however, may becentrally located and the valve G supplied with the necessary weight onone side of the rod. The valve Gr is provided with lips above and belowon the opposite sides of its axis, which engage the bead I, which runsaround the interior of the sleeve B. From the surface plate a bracket .Iprojects downwardly, said bracket being either cast integrally with thesurface plate or bolted thereto, and to the foot of this bracket ispivoted a lever K, provided with a serrated sector I., which projectsabove the surface plate E, and with the curved arm M, which engages thesmaller segment of the valve G. Instead of pivoting this lever to thearm J, depending from the surface plate, it may be pivoted to a boss J',either cast with or 4 otherwise fastened to the side of the box A at theproper point, as shown in Fig. 3. The lever K is held against itspivot-point and the'edge of the slot in the surface plate withsufficient friction to hold it and the valve in whatever position it maybe placed. It is evident that by pushing the sector L to the left thearm M will be thrown to the right and will press the segment of thevalve with which it engages downward, throwing the other segment up andproducing a corresponding opening of the valve, the extreme throw oft-he sector L causing the valve to be opened to its fullest extent. Theoverbalancing of the valve causes it to close when the sector is movedto the right. By this construction the surface plate is left free forremoval without the valve, and it is rendered light in Weight, so that awoman can lift it for cleaning out the valve-box, the valve remainingclosed and the hot air shut off during this operation. This constructionalso facilitates the taking up aud putting down of carpets withoutbreaking the pipe connections. In ordinary practice a register-pancontaining valves or shutters is bolted to the surface plate, and thisregister-pan is either connectedv directly IOO to the heater-pipe or setinto a box which conneots with the heater-pipe. In order to remove thesurface plate, the entire pan must be lifted out, which leaves theheater-pipe open for the hot air to drive up while the register is soremoved. Dust accumulates in these register-pans, and in order to cleanthem out the bolts must be removed and the pan separated from thesurface plate. By my arrangement this difficulty is avoided. I combinethe register-pan and the register-box in one piece. I permanently securethe register-box in place and avoid any necessity of breaking the jointwith the heater-pipes.

The registerbox may be made of sheet metal stamped or otherwise bentinto shape, or it may be made of cast-iron.

Having thus described my invention, what I desire to secure by LettersPatent isl. A register comprising a fretwork surface plate, aregister-box provided with a sleeve to connect with the heater-pipe, abuttery valve or damper pivoted in the sleeve, and an operating-leverpivoted in the register -boX, one arm of said lever projecting ter-boxand sleeve, a fretwork surface plate removably attached to said box, abutterfly valve or damper pivoted in said sleeve, and an operating-leverpivoted at one side of the register-box, one arm o f said leverprojecting through a slot in the surface plate, and the other arm beinggiven a compound lateral and inward bend whereby its end is brought intooperative engagement with a segment of the valve and caused to travel inan arc transverse to the valve in its several positions.

In testimony whereof I have aflixed my signature in presence of twoWitnesses.
